Determinants of Anemia among women in Uganda: further analysis of the Uganda demographic and health surveys

Background: Anemia is a public health problem in many developing countries. It affects a sizable proportion of women of reproductive age. Anemia increases the risk of morbidity and mortality from infectious diseases, and can lead to poor fetal outcomes, and low productivity. This study examined the trends and determinants of anemia among women of reproductive age in Uganda. Methods: This study analyzed data from the Uganda Demographic and Health Surveys conducted in 2006, 2011, and 2016. The study was based on 10,956 weighted cases of women age 15-49. Bivariate analysis and multiple logistic regression analysis examined the association between the outcome variable and the determinants. Potential determinants of anemia in women were selected based on literature. Results: The results of the analysis show that anemia decreased in Uganda between 2006 and 2016, but with an increase between 2011 and 2016. The overall prevalence of anemia among women was 50, 23, and 32% respectively in 2006, 2011, and 2016. Women who were pregnant at the time of the survey had higher odds of being anemic across the surveys (OR 2.00, 95% CI 1.49-2.67; OR 1.47, 95% CI 1.02-2.10; OR 1.33, 95% CI 1.07-1.65). Women in households with nonimproved sources of drinking water also had higher odds for anemia (OR 1.32, 95% CI 1.09-1.61) in 2016. Wealth index, region and age were also significantly associated with anemia in women. Conclusion: In order to reduce anemia in women, there is need to target pregnant women during antenatal and postpartum visits, and ensure that nutrition education during such visits is supported. There is also need to ensure sustainable household access to safe water. This should be combined with interventions aimed at enhancing household wealth.
